Answer;
-Mixtures of dissolved compounds and gases thought to be similar to earth's early atmosphere
Explanation;
-Miller and Urey, conducted an experiment which demonstrated that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere. They designed an apparatus which held a mix of gases similar to those found in Earth's early atmosphere over a pool of water, representing Earth's early ocean.
-Therefore,to recreate an environment for biosynthesis, scientists included all of the following,unstable chemical conditions.sparks and also dissolved compounds and gases thought to be present in the early atmosphere.
